1/8 inch x 2 inch Black Steel Nipple

1/8" x 2" Black Steel Pipe Nipple – Manufactured for Industrial-Grade System Integration

The 1/8 inch x 2 inch black steel pipe nipple is designed for use in systems where strength, pressure resistance, and dimensional consistency are required. It features a seamless steel body with tapered NPT threads, making it suitable for a variety of non-potable fluid and gas conveyance applications including low-pressure steam, air, oil, and gas systems.

This nipple is fabricated in accordance with ASTM A53 specifications and threaded to meet ASME B1.20.1 standards, ensuring consistent joint compatibility across compliant components. Its black oxide coating provides moderate corrosion resistance in protected indoor environments, while the steel base material delivers the structural integrity expected in commercial and industrial systems.

Product Features

• ✅ Material: Schedule 40 black steel pipe conforming to ASTM A53 Type F or Type A.
• ✅ Connection: NPT male thread x NPT male thread – machined to ANSI B1.20.1 standards.
• ✅ Length: 2 inches overall with threaded engagement zones.
• ✅ Application Suitability: Common in natural gas, HVAC, compressed air, and low-pressure oil systems.
• ✅ Coating: Black oxide finish to resist oxidation in non-corrosive environments.

Installation Requirements

Use standard thread sealant or PTFE tape to ensure leak-tight joints. Torque should be applied using appropriate pipe wrenches to achieve proper sealing without over-tightening, which can cause thread deformation. For pressure-rated systems, pressure testing should be performed per applicable building and mechanical code requirements.

Typical Use Cases

This 1/8" x 2" black steel nipple is used in:

• • Natural gas and propane distribution piping
• • Compressed air and lubrication systems
• • Steam and oil transfer in mechanical rooms
• • Industrial process skids and equipment tie-ins

Regulatory Considerations

Black steel nipples are not rated for potable water systems due to potential internal corrosion. They should be used only in approved systems as specified by local plumbing, fuel gas, and mechanical codes.

The 1/8" x 2" black steel pipe nipple provides a reliable method for extending or adapting pipe runs in pressure-bearing applications. When specified correctly, it delivers stable performance with minimal maintenance over time in compliance with industry standards.
